Version: (using KDE KDE 3.5.6) Installed from: SuSE RPMs I don't know if this is technically possible but it would extremely useful. Mechanism similar to KDE session and recent application in Kmenu. Let's say I am reading two pdf documents, and I want to remember those because they are important. So I add a bookmark (system) for the document (not application) and in KMenu I see entries in section: bookmarked documents. Documents could be of course audio files, movies, pdf files, anything. When the user choose the bookmarked document, the appropriate application is executed and the document is loaded. Here the biggest problem (I think) is to get the filename of the opened (current) document.
Bookmarked documents or "stickied"/"pinned" documents is something I proposed in the SimpleMenu rewrite: https://phabricator.kde.org/T12192 Hopefully it will eventually get done!
